+### Feeds options
+
+Feeds are available in ATOM with `?do=atom` and RSS with `do=RSS`.
+
+Options:
+- You can use `permalinks` in the feed URL to get permalink to Shaares instead of direct link to shaared URL.
+    - E.G. `https://my.shaarli.domain/?do=atom&permalinks`.
+- You can use `nb` parameter in the feed URL to specify the number of Shaares you want in a feed (default if not specified: `50`). The keyword `all` is available if you want everything.
+    - `https://my.shaarli.domain/?do=atom&permalinks&nb=42`
+    - `https://my.shaarli.domain/?do=atom&permalinks&nb=all`
+
+### RSS Feeds or Picture Wall for a specific search/tag
+
+It is possible to filter RSS/ATOM feeds and Picture Wall on a Shaarli to **only display results of a specific search, or for a specific tag**.
+
+For example, if you want to subscribe only to links tagged `photography`:
+- Go to the desired Shaarli instance.
+- Search for the `photography` tag in the _Filter by tag_ box. Links tagged `photography` are displayed.
+- Click on the `RSS Feed` button.
+- You are presented with an RSS feed showing only these links. Subscribe to it to receive only updates with this tag.
+- The same method **also works for a full-text search** (_Search_ box) **and for the Picture Wall** (want to only see pictures about `nature`?)
+- You can also build the URLs manually: 
+    - `https://my.shaarli.domain/?do=rss&searchtags=nature`
+    - `https://my.shaarli.domain/links/?do=picwall&searchterm=poney`
